Tol all whom 'it mcy concern.'

Be it known that I, ALEXAN inni Win'roN, a citizen of thc United States, residing,y at Cleveland, in the county of Cuyzihoa and State of Ohio, have invented new on: nselnl Improvements in Spiirliing Meclninisin for Explosive-Engines, ol which the following is The accompanying drawing is ii socl'ionalY view; ol" a device embodying niy. invention.

My invent-ion pertains to n inuke und hrcuk niec'hanisni particularlyr intended for use in connection with thc jiiiiip-spnrk principle ol ignition, find which is so well unf crstood hy thoe skilled in the nrt, that the sparking plug (which foiiii no purl ol' my procent invention) is ncitlici: shown or described heroin.

Referring now to tho drnwiw, .l indicntvs a Shaft which cni'rirs ai com s ccvc 2. 'lic shaft 2 is oliciiitivcly croiiin-i-.lcd (in `:in i' dcsircd inanincr) with tho cngiiic sliiil't und iis here sliowii, the dcvicv is intended [o lic usod in cornice-lion with i two-cylinder cngiiir, and hence` fue cion sleeve 2 is )rovided with two caiiris 2i, one lioi' eiici v vlinilci'. lrv is also well undciistood tlint :lic cnin simil l of the sparking inccliunisin is so tiincd with the oiigine sniil't :is lo c-.nlisc thvY minis Il to opi-.inte thc niiikc und lirciik dcvicc (lio lio pi'ci-icntly described) ci thc iroper nioincnl. 'llie dcvice is also iiitenilcd to lic iiscd prii'icipiilli, in connection with :in explosion engine ol the four-cyclo typo, though il nniy lic uscd willi explosion ciigiins of oilivr typos without nlfecting infr iiivrniion.

A caso -1 is ronrvnricully :iri'nngod on llio.'

shaft] midis iidnpIi-d to loosrilliilcd around the slnlll, through 1hr iiicdiniii ol' :i suitnlilc connection Y 5 iunder Iliicontrol ol' tho operator. (.ni'rird li thv uns@ Ll is n loven' 6 pivoicd nl u point 7. This lcvfr G is vil'iriitcd h v the coins 3 and the lovcr is proieruhl f provided with ai anni engaging projection The [roc end of the lever 6 carries :i contact point 9 und this Contact point l) is `adapted to engage u contact oint l0 when the lover is forced outward )Y one of tllc cams 3 and to dios closelhe circuit, and to break the circuit when one oi thc cams 3 has passed the projection 8 und the lever is forced Dby the s n'ingv pin 11 into the position sho-vm iii the i'nwiii Flic contact point 10 is i'iorinally force( inward through the medium ol* the spring 12 and the limit of the inward movement of'tlic contact is controlled by inciiiis of :in ndjustulilc nut )4 carried by the ont-cr sci'ev.'-threiided end oi the stein 15, Tho principal advantage of this construction is, t-lmt n robbing Contact is effected between thel conliicl points l) and 10. This result is brought idioot lroin the iict that the moveineiilof tho frcc ond ol the lever (i is greater than the distance between thc contact points thus forcing tlic spring dcprcssed conta/ctpoint outward, fuif lalso owing to the fact that the lever (i is pivotod so that thecontiwt Q swings in tho nrc of ii circle in respect to thc Contact l0. A further odvfintnre of' this construction is, that hy inenns of t e iidjust :dile not 14, the contact I() can be; allowed. to move inward 'as it liccoinci; liurn'cd or wom iiwiiy. The. riihhing net-ion insures a; bright contact surface inid hoops thc contact points in iropcr shape for the best results.

t will hc oliscrvcd that the lever 6 cori-ying the contiict $1 extends eccentrically m i'csg'icci to tho shiil't l, ond that the contact 10 extends in n tangential direction in respect lo said slnilt. This nrrniiffenicnt causes the. contact U to haii-'c coiisiferrdile transverse movement in respect lo the contact 10, und in 'practico it is found that the transverse niovcinent is suflicicnt lo koop the contacts clcini und bright, which is so essentinl to good results.

By incuns of the oscillation ol the ciisc 4 iii respect to the com shiifl l, thc level' 6 con lic inovod in ii direction around thc shaft so 'iis to conso the minis 3 lo open-utc linA lever curly or Inte iii rnb-poel. to thc position ol thc cugino piston und thus varying what is known in thc iirt iis thc ignition 10nd` l`li1l viirinlion ol thc ignition lood iii explosion vngincs for niotor vrliiclcs, is found vor) dcsirrilile, und man)l wuys lnivc heen dcviscd l'or ii ccoiiiplishinihr Illini result. The iiiciins lici'c shown is simple and eil'octive, :ind ennlilcs thc opcinlor lo Sturt thc origini. with n f e luto lend to prevent thc cnginc kicking nickwiird, und thon to afterward ud vunc-c the lend, which is Found necessnry lo olilnin the ninxinnnn power und the innxiinuin speed of' the engine, li thc lend of the cugino is set at the advance point, the operator in starting his engine, is likely to be "kicked" unless he is skilled in the starting of engines oi In some motor Vehicles the varialead is automatically controlled, means here shown 1s a Jositive under the contro ol the this ty e. tion o the while the device positively operator. e

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is

1. In a device of the character described, the combination of a rotating shaft carrying cams, a casing surrounding the shaft, a lever pivoted to the casing and engaging the shaft, Intermediate its ends, means for holding said lever in-engagemcnt with said shaft, a contact point carried by the lever and extending in :Ft-transverse direction in respect to the shaft, and a spring actuated contact extendingin a correspondingr direction to that of the contact carried by the lever, and the pitch ofthe cams being greater than the distancel between thc contacts, whereby thc contacts have a longitudinal engagement and a rclative transverse movement.

2. ln a device of the character described, the combination of a rotating shaft carrying cams, a casing surrounding the shaft, a spring-actuated pivoted lever carried by the casing and engaging the shaft intermediate its ends, a contact point carried b v the free end of the lever and extending in a transverse direction in respect to the shaft, and a spring Contact extending in a corresponding direction to that of the contact carried by the lever, and the pitch of the cams being greater' than the distance between the contacts, whereby the contacts have a longitudinal and a relative transverse movement.

3. 1n a device el the character described, the combination of a rotating shaft carrying cams, a casing surrounding the shaft, a lever pivoted to the casing and engaging the shaft intermediate its ends, e spring actuated plunger bearing on the lever and normally ioldingit upon the shaft, a contact point carrie( by the lever and extending in e transverse direction in respect to the shaft but on opposite sides of the lever to that en` gaged by the shaft, and a spring-actuated adjustable contact extending in a corre` spending direction to that of the Contact earned by the lever, and the pitch of the cam being greater than the'distance between the contacts, whereby the contacts have a longil tudinal engagement and a relative transverse l movement.

4. [n a device ofthe character described, l the combination of a rotary shaft carryimr i cams, a casing surrounding said shaft an( loosely mounted thereon, means for holding the easing in its adliusted position on the l'shaft, a lever pivote: within the casing and f engaging the shaft intermediate its ends, a l spring actuated plunger hearing on the lever and normally holding it in engagement with the shaft, a contact point carried by the outer free end of the lever, a sprin r actuated Contact extending in a correspon( ing direc` i tion to that of the contact carried by the lever, and carried by the casing, and said y Contact having a screwstln'eaded stem, and

l a nut. on said stem for adjusting the same subl l stantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
